1. Overview

MICR (Magnetic Ink Character Recognition) is a process by

which documents are printed using magnetic ink and special

fonts to create machine readable information for quick document

processing.

Although traditionally MICR has been used to print accounting

and routing information on bank checks and other negotiable

documents, the magnetic encoding lends itself to any form of

document processing.

The following figure shows a check with a MICR line. This line

contains block-shaped numbers running along the bottom of the

check, and non-numeric characters called “symbols.” This entire

string of numbers and symbols is printed using magnetic ink.

Overview

1-2 Generic MICR Fundamentals Guide

A brief history

Originally, checks were processed manually. However, by the

mid-1940s the banking system became inundated with paper as

society grew more mobile and affluent. Finding a means of

handling the growing number of paper documents became vital

to bankers. The banking and electronics industries searched for

a standard process that could be used in all banks throughout

the country.

In the mid-1950s, the first automated processing of checks was

initiated. The system that is now known as MICR was developed

by the Stanford Research Institute, using equipment designed by

the General Electric Computer Laboratory. The E13B MICR font

was also developed.

The specifications for producing the E13B font using magnetic

ink were accepted as a standard by the American Bankers

Association (ABA) in 1958. In April 1959, the ABA issued

Publication 147, The Common Machine Language for

Mechanized Check Handling.

Deluxe Check Printers had the task of translating the

specifications into a working process. By the end of 1959,

Deluxe successfully produced checks using magnetic ink.

In countries throughout the world there are groups that set

standards and dictate the design specifications for document

encoding, processing equipment, and quality criteria for MICR

printing. Some of these are:

• American Banking Association (ABA)

• American National Standards Institute (ANSI)

• United Kingdom—Association for Payment Clearing Services

(APACS)

• Canadian Payments Association (CPA)

• Australian Bankers Association (ABA)

• International Organization for Standardization (ISO)

• France—L'Association Francaise de Normalisation

Overview

Generic MICR Fundamentals Guide 1-3

In 1963, the American National Standards Institute (ANSI)

accepted the ABA specifications, with minor revisions, as the

American standard for MICR printing. The ANSI publication

covering these standards is Print Specifications for Magnetic Ink

Character Recognition, first issued in 1969. Although compliance

with the standards is voluntary in the U. S., the banking industry

considers them to be the definitive basis for determining

acceptable quality of a MICR document.

Another MICR font, called CMC7, was developed by the French

computer company Machines Bull and has been the official

French standard since September 1964. The CMC7 font is also

used in other countries, including Italy, Spain, and Brazil. Like the

E13B font, CMC7 is a magnetically readable font, but with a

different character design and recognition criteria.

Some countries also use OCR-A or OCR-B, which are optically

read check processing fonts. These fonts do not need to be

printed with magnetic ink in order to be processed. The following

table shows which countries use the four check printing fonts.

Overview

Generic MICR Fundamentals Guide 1-5

Recognizing significant market value in combining the

advantages of electronic laser xerography with MICR technology,

Xerox initiated investigations in late 1979 and early 1980. Early

efforts at the Xerox Webster Research Center concentrated on

basic material physics. The objective was to provide a

xerographic dry ink and developer that would produce high visual

quality images that could be read using the standard banking

reader sorter equipment.

Xerox’s MICR printing products combine the following:

• A modified xerographic engine

• A unique magnetic materials package

• The standard ANSI and ISO MICR character sets

The Xerox MICR systems meet ANSI, CPA, and ISO

specifications for automatic check handling.

Why MICR?

MICR was chosen by the ABA because it can be read accurately

by machine, it uses existing printing technology, and the printed

documents are durable to withstand mutilation.

A MICR encoded document can be read through overstamping,

pen and pencil marks, oils and greases, and carbon smudges.

However, MICR printing is one of the most quality-conscious

application areas within the printing industry. It meets ABA

security requirements for negotiable documents. MICR is the

only system that produces reliable results at high processing

speed.

Check printing capabilities

A Xerox MICR printing system with a magnetic material package

and MICR fonts can print a character line at the bottom of a

check form that is machine readable by standard banking reader

sorter equipment. On blank security paper, the Xerox MICR

printing system can produce the entire check image, including

the form, all fixed and variable data, logos and signatures, and

the MICR line, in a single pass.

Overview

1-6 Generic MICR Fundamentals Guide

The printing process is one small part of the total processing

procedure for a MICR printing system user. Quality and accuracy

of the check documents must be closely controlled during

printing to prevent problems from occurring when the document

is processed off-site.

Check processing procedure

All checks impact at least three parties:

• The person who writes the check

• The person to whom the check is being paid

• The bank at which the check writer has an account

Depending on where and by whom the check is deposited, how

the check is processed, and how the check is handled for funds

clearance, many different parties can handle the same check.

Fraud can occur at any of the steps or access points in this

process.

The following steps, illustrated in figure 1-2, trace a document

through a series of corporate and banking system procedures

typical of the MICR environment.

Overview

Generic MICR Fundamentals Guide 1-7

Figure 1-2. Life cycle of a check

Overview

1-8 Generic MICR Fundamentals Guide

1. The check printer (1) produces a blank check that will be

completed later. This check includes the static data that is

needed for a negotiable document:

• Financial institution name and address, issuer name and

address, check form, company logo, etc.

• The MICR line, containing the account and routing

information that is needed to process the check

• Other audit, account, and report information as required

by the customer

2. The customer (2) adds the transaction information—payee,

amount, and date—and authorizes the funds transfer with a

signature.

NOTE: When using a MICR laser printer, steps 1 and 2 may

happen simultaneously.

3. The completed check is transferred to the payee (3), who

deposits it in the bank of first deposit (BOFD). The payee may

receive the check in person, by mail, or through a third party.

A third party check may require a second endorsement.

4. Deposits (4) are made in several ways: through a teller, using

an automated teller machine (ATM), using a drop box, or

through a postal lock box. Deposited items are accompanied

by a deposit ticket that lists and totals the items and identifies

the payee account.

This is the entry point for the automated payment processing

system.

5. The BOFD encodes the amount of the check in the MICR line

(5) and balances the check against the deposit ticket to verify

that the correct amount is being credited to the payee

account (proof of deposit).

6. MICR documents that are printed on a Xerox MICR printing

system are usually corporate paychecks, stock dividend

checks, etc. After printing, these type of documents require

additional processing using a high-speed device called a

“reader sorter.” The reader sorter identifies each magnetized

character and symbol of the MICR line using logical analysis

algorithms of the electronic wave patterns that the characters

produce.

In the “capture pass,” checks are read in a reader sorter for

the first time (6). At this time, they are sorted into checks

drawn on the BOFD, known as “On-us items” (8), and checks

drawn on other banks.

Overview

Generic MICR Fundamentals Guide 1-9

7. Checks drawn on other banks are sent to the payor bank

through a clearing (7) arrangement. The check may be

cleared through the Federal Reserve, a correspondent bank,

a clearing house, or directly by the issuing bank.

The payor bank also balances the check against the deposit

ticket (proof of deposit) (7a) to verify the check amount, and

performs its capture pass (7b) on the reader sorter in order to

identify the issuer account (7c). (Refer to the “Proofing

checks” section of chapter 5 for more information on this part

of the process.)

8. In most cases, the check is debited from the issuer account

and moved to bulk filing (8), where it is stored until time for

monthly statement rendering.

From this point forward, an On-Us item is treated the same as

one that was cleared to another bank.

Two exceptions may occur:

• If the payor bank does not honor the check, it is returned

(9) through the BOFD to the payee. The amount is then

deducted from the payee account.

• During reconciliation, the account holder may discover a

discrepancy (10) between its records and those of the

bank. Their bank then researches any discrepancies.

NOTE: Account holders may contract with their banks to

perform reconciliation before clearing the check.

Production cycle of a check

The check production process starts as soon as the need is

identified. Design requirements should comprehend purchasing,

distribution, warehousing, manufacturing, internal and external

processing requirements, and the needs of the check issuer.

Banks frequently require new corporate accounts to submit

checks for approval before the banks approve the account.

The following steps, illustrated in figure 1-4, describe the typical

process that is required before the first negotiable checks are

delivered to the payee.

Overview

1-10 Generic MICR Fundamentals Guide

Figure 1-3. Check ordering and production cycle

1. Design requirements are defined for a new account.

2. Requirements are passed to application development.

3. Samples pass internal quality checks.

4. Samples are forwarded to the bank for approval.

5. Any problems are referred to application developers, who

ensure that the problems cannot occur in production.

6. After approval by the bank, the check design becomes

available for routine production.

7. Variable check data is prepared for incorporation.

8. The checks are printed.

9. The printed checks are inspected.

10.Any problems are reported to the source for correction and

reprinting.

11.When they have passed bank validation and quality

inspection by the issuer, the checks are issued to the payee.
